SAFETY-ATTENTIONS

Clean the unit with a soft cloth or dry rag. Do not
use chemical solvents, flammable insecticide, sprays
or the likely products to clean the unit. Otherwise,
damage to the unit may be incurred.
Do NOT install the indoor unit close to cooking or
ventilation. Otherwise, unit efficiency will be
affected seriously.
Stop and disconnect the unit immediately after finding
the unit at anomaly oder (burning, scorching )
Close doors and windows. If you use the unit for a
prolonged period and the ambient air turns to be
unpleasant, open a door or a window for a moment
to refresh the atmosphere.
Subject to Continuous Engineering Improvement without Prior Notice.
Intall the unit in accordance with all the safety codes
applied. The unit cannot be installed in a wash-
house or where flammable gas could ocurr. The unit
must be electrically protected by qualified circuit
breakers.
Do NOT install the unit in places at risk of farmable
gas leakage. If electric spark is incurred in the unit
accidentally, it could cause a fire or an explosion.
Do NOT use the system for other non-HVAC purpose.
Do not store it along with food or painting or other
chemicals.
Do NOT use the unit in cool/dry during a prolonged
period at high moisture (higher than 80%).
Condensation could be formed on the indoor unit
casing if a door or window is open or the indoor
humidity is high.

OPERATING TEMPERATURE RANGES

Operate the unit in the temperature ranges shown below. It is not recommended
to operate the unit out of these ranges, otherwise warranty will be voided.

Important Notes:
1). Working temperature ranges listed above are guaranteed for units to work properly, though these temperature
ranges are conservative.
2). Units may still work well out of the guaranteed working temperature ranges, as long as they are installed
properly and are still in good conditions within design envelop.
3). Units are designed for mild low temperature AC cooling applications. Units come with low temperature control
to protect againt too low pressure when running for AC cooling in weather colder than 45F and warmer than
35F. In this temperature ranges, units may not need to add refrigerant and/or jumper at low pressure switch. If
units are to be used for cooling only below 35F, then better to check and add refrigerant and jumper at low
pressure switch. Situation varies upon indoor load and indoor unit installation conditions such as TEX type,
elvation vs outdoor unit, copper line set size and length, refrigerant level and leakage level.
4.) Units may still work HP heating well way below 17F, though exact temperatures are not listed. Units will defrost
during HP heating model in cold weather. Suction (bigger) pipe should be hot and the discharge (smaller) pipe
should be warm at outdoor unit during HP heating mode, if everything is right.
5.) Optional component Wind Baffle installed at fan discharge side on the cabinet is designed to keep from cold air
blowing into propeller fan blade against airflow, and so help unit work better in both AC cooling and HP heating
mode in colder weather ragnes.
NOTES: Since ductless system is not designed to incorporate or use with ducted return or discharge tunnels,
one single-zone unit SHALL NOT be used to take care of the cooling or heating load of more than one-story
room. Several single-zone ductless systems or multiple-zone ductless systems shall be used in this regard.
